Description

Technical Field

[0001] The utility model relates to the technical field of high-rise building facade construction, and particularly relates to a traction type ring rail hoisting device for constructing the facade curtain wall of high-rise buildings. Background Technique

[0002] When the main structure of a high-rise building is completed, due to the high building height, in order to solve the problems of vertical and horizontal transportation and installation, a hoisting device with an outer ring rail needs to be used to install the curtain wall. Its general process is as follows: taking a certain floor in the middle and upper part of the building, such as the 10th floor, as the base floor, fixing a cantilever beam perpendicular to the floor edge at a certain distance on the base floor slab, so as to arrange a circle of multiple cantilever beams outside the base floor slab, then fixing a section of I-beam lifting rail perpendicular to the cantilever beam on each cantilever beam, and connecting the heads and tails of all the I-beam lifting rails to form a circular lifting rail around the outside of the base floor slab, that is, the outer ring rail. The outer ring rail is divided into straight sections and arc sections, the arc section is located at the floor corner, and the straight section is parallel to the straight edge of the floor. A hoisting vehicle is slidably fitted on the outer ring rail, a winch is installed on the hoisting vehicle, and a lifting tool for lifting curtain wall panels such as glass panels and aluminum panels is provided at the lower end of the winch traction rope; to ensure stability, multiple upper hanging ring assemblies also need to be embedded in the floor slab of the upper floor of the base floor, such as the 11th floor, and the upper hanging ring assemblies correspond to the cantilever beams one by one, and each upper hanging ring assembly is reinforced with a tie rod at the outer end of the corresponding cantilever beam. Thus, the ring rail hoisting device is installed. Then, the curtain wall panels are hoisted layer by layer from bottom to top, that is, driving the hoisting vehicle to travel around the outer ring rail for one circle, hoisting all the curtain wall panels on the a-th floor below the base floor, such as the 3rd floor, in place, and then driving the hoisting vehicle to travel another circle to hoist all the curtain wall panels on the (a + 1)-th floor, such as the 4th floor, and so on... until all the curtain wall panels on the floor below the base floor are hoisted. For example, if the 10th floor is used as the base floor, then all the curtain wall panels on the 9th floor are hoisted.

[0003] For the sake of convenient expression, the floor where the curtain wall panel is being hoisted is called the hoisting floor.

[0004] If the building facade is completely vertical, there is no need to make any adjustment to the hoisting device and the cantilever beam, but directly hoist layer by layer upward. However, if the building facade is not vertical, such as a tower-shaped structure with a smaller upper part and a larger lower part, or a waist-shaped structure with larger upper and lower parts and a smaller middle part, it is necessary to replace the cantilever beam according to the concave and convex conditions of the facade of different floors to change the cantilever distance. That is, the cantilever distance is long when hoisting the relatively convex floor, and the cantilever distance is short when hoisting the relatively concave floor, so as to ensure that the lifting point is always at an appropriate distance from the edge of the hoisting floor, so that workers can reach the curtain wall panel standing on the floor edge.

[0005] Therefore, there are the following defects when hoisting buildings with concave and convex facades in the prior art. First, the process of replacing and adjusting the cantilever beam is cumbersome. The cantilever beam in the prior art is fixed to the floor of the base layer by multiple U-shaped buckles and anchor bolts. When replacement and adjustment are needed, since the total lengths of the beams are different and the anchoring lengths inside the beams are also different, the anchoring points of the anchor bolts on the floor are different. Therefore, it is necessary to remove the old anchor bolts and drill new anchor bolt holes in the floor, which makes the process of replacing the cantilever beam cumbersome, time-consuming and laborious. Moreover, too many holes drilled in the floor also increase the workload of later repair and plugging. Moreover, more importantly, the outer ring track is fixed on each cantilever beam. Therefore, before replacing the cantilever beam, it is necessary to remove all the outer ring tracks. After the cantilever beam is adjusted and replaced in place, it is necessary to splice the outer ring track again. That is to say, every time the cantilever beam is adjusted, it is necessary to disassemble and reinstall the outer ring track, split it into each section of I-beam lifting track and remove all the I-beam lifting tracks from the corresponding cantilever beam. After the new cantilever beam is adjusted and fixed, it is necessary to fix each section of I-beam lifting track to the corresponding cantilever beam again and reconnect each section of I-beam lifting track into the outer ring track. Its disassembly and installation process is very cumbersome, time-consuming and laborious. The disassembly requires cutting section by section, while the installation requires welding and grinding section by section. The workload of disassembling and installing the outer ring track is even greater than that of replacing the cantilever beam. Moreover, it is high-altitude operation, very inconvenient, and there are also safety hazards of falling from a height or falling objects.

[0006] Of course, in addition to the above-mentioned scheme of moving the cantilever beam, when hoisting the curtain wall of buildings with concave and convex facades in the industry, there is another treatment idea, that is, installing multiple cantilever beams and outer ring tracks on multiple different floors. For example, outer ring tracks are installed on the 10th, 13th and 18th floors. Since the concave and convex conditions of the facades of the above-mentioned floors are different, the cantilever distances of the cantilever beams fixed on the above-mentioned different floors are also different, so as to meet the needs of hoisting the curtain wall of buildings with concave and convex facades. However, obviously, the above treatment idea requires setting up multiple circles of cantilever beams and outer ring tracks with different storey heights, which requires greater labor costs and material costs, the labor intensity and workload are doubled, and the construction period is also longer. Therefore, construction enterprises are often difficult to afford, so the value of popularization and application is not great. Utility Model Content

[0007] The technical problem to be solved by the present utility model is to provide a traction type ring track hoisting device for high-rise building curtain walls during construction, which can make the hoisting point close to the edge of the floor of the hoisting layer without replacing and adjusting the cantilever beam, let alone disassembling and installing the outer ring track, thus greatly reducing the workload.

[0008] The technical solution of the present utility model is to provide a traction type ring rail hoisting device for constructing curtain walls of high-rise buildings. It includes a basic floor slab. A cantilever beam is installed at a certain distance on the basic floor slab. A section of I-beam lifting rail is fixed to each cantilever beam. All the I-beam lifting rails are connected end to end to form an outer ring rail that surrounds the basic floor slab in a circle. A hoisting vehicle is slidably engaged with the outer ring rail. A winch is installed on the hoisting vehicle. A sling is provided at the lower end of the winch towing rope. A plurality of upper hanging ring assemblies are embedded in the floor slab of the upper layer of the basic floor. The outer end of each cantilever beam is connected to the corresponding upper hanging ring assembly through a pull rod. A circle of inner ring rail is fixed to the edge of the floor slab of the lower layer of the basic floor. The inner ring rail is formed by connecting multiple sections of I-beam slide rails end to end. A towing vehicle is slidably engaged with the inner ring rail. A transverse driving cylinder protruding outward from the basic floor slab is installed on the towing vehicle. A rigid rope sleeve for pulling or pushing the towing rope inward or outward is provided on the piston rod of the transverse driving cylinder.

[0009] Compared with the prior art, the above hoisting device has the following advantages.

[0010] The working process of the hoisting device is as follows. Install the cantilever beam, outer ring rail, and hoisting vehicle on the basic floor slab. Embed the upper hanging ring assemblies in the floor slab of the upper layer of the basic floor and connect the upper hanging ring assemblies to the corresponding cantilever beams through pull rods. Install the inner ring rail and the towing vehicle on the floor slab of the lower layer of the basic floor. Then hoist the curtain wall panels layer by layer from bottom to top. Deal with them differently according to the concave and convex conditions of the elevation of the hoisting layer relative to the basic floor. If the elevation of the hoisting layer protrudes outward, push the rigid rope sleeve outward through the transverse driving cylinder to move the sling point of the towing rope outward. If the elevation of the hoisting layer is concave inward, pull the rigid rope sleeve inward through the transverse driving cylinder to move the sling point of the towing rope inward. Thus, the distance between the sling point of the towing rope and the edge of the floor slab of the hoisting layer is reasonable. The hoisting vehicle travels around the outer ring rail for one circle to hoist all the curtain wall panels of the hoisting layer in place. And the towing vehicle also moves along with the hoisting vehicle, travels around the inner ring rail for one circle, continuously pulls or pushes the towing rope inward or outward, so that the distance between the sling point of the towing rope and the edge of the floor slab of the hoisting layer is always maintained at a reasonable distance.

[0011] In this application, the tractor rotates synchronously with the hoisting vehicle, and synchronously pulls or jacks the towing rope to move the suspension point, so that the suspension point of the towing rope and the edge of the hoisting floor are maintained at a reasonable distance, ensuring that workers can reach the hoisted curtain wall panel by stretching their hands when standing on the edge of the hoisting floor. The key is that the technical solution of this application bypasses the process of adjusting the cantilever beam, disassembling and assembling the outer ring rail, and solves the problem with little effort, omitting a series of cumbersome and complex processes such as cutting the outer ring rail into each section of I-beam hoisting rail, removing all the I-beam hoisting rails from each cantilever beam, removing the old cantilever beam, replacing it with a new one, screwing the ground anchor bolts, re-fixing the I-beam hoisting rail on the new cantilever beam, welding each section of the I-beam hoisting rail back into a ring and grinding, etc., greatly reducing the labor cost and labor intensity, significantly improving the hoisting efficiency, and significantly shortening the construction period. Moreover, compared with the scheme of setting up multiple cantilever beams and outer ring rails on different floors, the technical solution of this application significantly reduces the labor cost and material consumption cost, has less labor intensity, is more convenient and faster in construction, and has a shorter construction period.

[0012] Preferably, the specific structure of the tractor is that a chassis is provided on the upper part of the tractor body, and the inner side of the chassis protrudes inward from the body to form a convex part. The cylinder body of the transverse drive cylinder is fixed to the chassis through an arc-shaped buckle, and the inner end of the transverse drive cylinder extends to the convex part; the inner motor and the speed reducer of the tractor are both fixed to the convex part. The advantage of this structure is that since the drive cylinder extends out of the floor, there is bound to be a tendency for the vehicle body to overturn outward; therefore, a convex part is specifically set on the vehicle body chassis, which not only provides an assembly space for the inner motor, but also increases the counterweight on the inner side of the vehicle body, facilitating the balance of the vehicle body; and the inward convexity of the chassis increases the overlapping contact area with the drive cylinder, ensuring the firm installation of the drive cylinder and shifting the center of gravity of the drive cylinder inward, further offsetting the outward overturning tendency.

[0013] Preferably, the tractor body is in an inverted U shape, and main pressure rollers are commonly connected to both side walls of the body. Inner limiting wheels and outer limiting wheels are respectively provided on both side walls of the body; the main pressure rollers roll on the top surface of the upper flange plate of the inner ring rail; the inner limiting wheels and the outer limiting wheels abut against the bottom surface of the upper flange plate of the inner ring rail; the above structure can ensure that the vehicle body rolls smoothly along the inner ring rail, and the inner and outer limiting wheels are used to hold the vehicle body against the inner ring rail, effectively preventing the vehicle body from overturning inward or outward.

[0014] As a further preference, the top plate of the body is welded to the chassis, and a trapezoidal steel plate is provided between the convex part of the chassis and the inner side wall of the body; the lower end of the trapezoidal steel plate and the lower end of the inner side wall are commonly welded with an inner protection steel plate, and the outer side of the inner protection steel plate covers below the inner limiting wheel; the lower end of the outer side wall is welded with an outer protection steel plate, and the inner side of the outer protection steel plate covers below the outer limiting wheel. In this way, the inner and outer protection steel plates form a double insurance. In case the inner and outer limiting wheels fail, the spare inner and outer protection steel plates will hold the upper flange plate of the inner ring rail to prevent the vehicle body from overturning inward or outward.

[0015] As a further preference, two inner and outer anchor plates are welded to the lower flange plate of the inner ring rail at regular intervals. The two anchor plates protrude from the lower flange plate of the inner ring rail in the inner and outer directions respectively, and each anchor plate is fixed to the floor slab of the foundation layer through ground anchor bolts. In this way, the inner ring rail can be effectively prevented from tipping over inward or outward, the support for the tractor can be improved, and the pulling or jacking of the towing rope can be ensured to be firm and reliable.

[0016] As a further preference, the rigid rope sleeve is a steel rectangular frame. Inner and outer dumbbell wire rollers are rotatably installed at both inner and outer ends of the rigid rope sleeve respectively. The middle of each dumbbell wire roller is concave inward to form a groove, and the towing rope is stuck in the middle groove of the inner or outer dumbbell wire roller. In this way, no matter whether the rigid rope sleeve pulls inward or pushes outward, the towing rope can be accommodated in the middle groove of the inner or outer dumbbell wire roller, ensuring smooth and stable lifting of the towing rope.

Detailed Embodiments

[0022] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0023] Such as Figures 1 to 4As shown in the figure, the present utility model relates to a traction ring rail hoisting device for constructing curtain walls of high-rise buildings. It includes a foundation floor slab 1. At regular intervals, a cantilever beam 2 perpendicular to the edge of the floor slab is installed on the foundation floor slab 1. More precisely, the cantilever beam 2 is normal to the edge of the foundation floor slab 1. Each cantilever beam 2 fixes a section of I-beam rail perpendicular to the cantilever beam 2. All the I-beam rails are connected end to end to form an outer ring rail 3 that surrounds the foundation floor slab 1 in a circle. The outer ring rail 3 is divided into straight sections and arc sections. The straight sections are located outside the straight edges of the foundation floor slab 1, while the arc sections are located outside the corners of the foundation floor slab 1. A hoisting vehicle 4 is slidably fitted on the outer ring rail 3. A winch 5 is installed on the hoisting vehicle 4. The lower end of the traction rope 6 of the winch 5 is provided with a lifting tool for lifting curtain wall panels such as glass panels and aluminum panels. Multiple upper hanging ring assemblies 7 are embedded in the floor slab on the upper layer of the foundation layer. The outer end of each cantilever beam 2 is connected to the corresponding upper hanging ring assembly 7 through a pull rod 8.

[0024] A circle of inner ring rail 9 is fixed at the edge of the floor slab on the lower layer of the foundation layer. The inner ring rail 9 is formed by connecting multiple sections of I-beam slide rails end to end. The inner ring rail 9 is also divided into straight sections and arc sections. The straight sections are located inside the straight edges of the floor slab on the lower layer of the foundation layer, while the arc sections are located inside the corners of this layer of floor slab. At regular intervals, two inner and outer anchor plates are welded to the lower flange plate of the inner ring rail 9. The inner anchor plate 10 protrudes inward from the lower flange plate of the inner ring rail 9, while the outer anchor plate 11 protrudes outward from the lower flange plate of the inner ring rail 9. Each anchor plate is fixed to the foundation floor slab 1 through two ground anchor bolts.

[0025] A tractor is slidably fitted on the inner ring rail 9. The body 12 of the tractor is in an inverted U shape. The main pressure rollers 13 are jointly connected to the two side walls of the body 12. Inner limit wheels 14 and outer limit wheels 15 are respectively arranged on the two side walls of the body 12. The main pressure rollers 13 roll on the top surface of the upper flange plate of the inner ring rail 9. The inner limit wheels 14 and the outer limit wheels 15 respectively abut against the bottom surface of the upper flange plate of the inner ring rail 9 from the inside and outside.

[0026] A transverse driving cylinder 16 protruding from the foundation floor slab 1 is installed on the tractor. Specifically, a chassis 17 is welded to the top plate of the body 12 of the tractor. The inner side of the chassis 17 protrudes inward from the body 12 to form an inner protruding part 17.1. The cylinder body of the transverse driving cylinder 16 is fixed to the chassis 17 through three arc-shaped buckles 18, and the inner end of the transverse driving cylinder 16 extends to the inner protruding part 17.1. The inner motor 20 and the reduction box of the tractor are both fixed to the bottom surface of the inner protruding part 17.1. Multiple trapezoidal steel plates 21 are arranged between the inner protruding part 17.1 of the chassis 17 and the inner side wall of the body 12. The lower ends of the trapezoidal steel plates 21 and the lower ends of the inner side walls are jointly welded with an inner protection steel plate 22. The outer side of the inner protection steel plate 22 covers the lower part of the inner limit wheel 14. The outer side wall of the body 12 is welded with an outer protection steel plate 23 at the lower end. The inner side of the outer protection steel plate 23 covers the lower part of the outer limit wheel 15.

[0027] The piston rod of the transverse drive cylinder 16 is provided with a rigid rope sleeve 24 for pulling the towing rope 6 inward or pushing it outward. To increase the shear resistance and ensure firmness, the wall thickness of the drive cylinder is thickened to 20 mm, making the outer diameter of the drive cylinder reach 100 mm, and the wall thickness of the piston rod is thickened to 10 mm, making the outer diameter of the piston rod reach 60 mm. The rigid rope sleeve 24 is a steel rectangular frame. Inner dumbbell wire rollers 25 and outer dumbbell wire rollers 26 are rotatably installed at the inner and outer ends of the rigid rope sleeve 24 respectively. The axial middle of each dumbbell wire roller is concave into a groove. When the drive cylinder pushes outward, the towing rope 6 is stuck in the middle groove of the inner dumbbell wire roller 25; when the drive cylinder pulls inward, the towing rope 6 is stuck in the middle groove of the outer dumbbell wire roller 26.

[0028] The inner motor 20 of the tractor is a servo motor with adjustable speed. The outer motor of the hoisting vehicle 4 always runs at a constant speed. In this way, the worker can adjust the speed of the inner motor according to the actual situation to make the tractor run synchronously with the hoisting vehicle. For example, when turning, the speed of the tractor on the inner bend is slowed down and then accelerated after turning.

[0029] The hydraulic station 19 of the transverse drive cylinder 16 is fixed on the floor of the next layer of the base layer. In this embodiment, the hydraulic station 19 is fixed at the three o'clock position in the circumferential direction of the inner ring rail 9. After the tractor makes a full circle and returns to the starting point each time, the hydraulic station 19 is connected to the transverse drive cylinder 16 with a hydraulic pipe to adjust the stroke of the drive cylinder, so that the lifting point meets the requirements of the next lifting layer. Then the hydraulic pipe is unplugged, and then the tractor makes a full circle with the hoisting vehicle to complete the lifting of this lifting layer. After returning to the origin, the hydraulic station is connected again to make the next adjustment of the drive cylinder stroke.
